struction for ventilated buildings formed of sheet metal and structural steel.

More specifically it is the object of my invention to provide improvedslabs which are in a ventilated wall construction formed of sheet metal A further object is to provide in a building structure a ventilated wall formedl of sheet metal studdings and horizontally arranged sheet metal slats, and between the lowerend of the wall and the foundation a waterproong material ofa semi-plastic or yieldable nature wherein the lower end of the wall may be dation to overcome strains and twisting of the rmlv set on the founwall structure due to uneven upper surface of the foundation.

My invention consists Vin the construction, arrangement and combination of the various parts of the device, wherebysthe objects contemplated are attained, as hereinafter vmore fully set forth,

pointed out in my claims,

and illustrated in the accompanying drawing, in which: i

Figure 1 is a side elevation of a portion of a wall illustrating my invention.

Figure 2 is a vertical detail sectional view taken on the line 2-2 of Figure Figure 3 is a horizontal sectional view taken on theline3-3of1figure2.

Referring to the accompanying drawing, I have used the reference numeral l0 to indicate a concrete foundation terminating in a floor portion- 11. Supported on the upper tion is a strip of packing material 12 in which is formed a considerable amount of asphaltum such as used for expansion joints in concrete road work.

Laid on top of the packing strip 12 is an angle iron 13 having a horizontal ange 14 and a vertical ange 15. the foundationby means other anchoring devices.

The said angle iron is secured to of suitable bolts 16 or Carried by the flange 14 is a. series of vertically arranged studdings 17 formed of sheet metal folded to have the form of a V in cross section.

The edges of the side members of the studdings have laterally extending flanges 18. The lower` edge of the foundaends of the flanges 18 are riveted or otherwise secured to the vertical flange 15 of the angle 13. A plate 19 formed of angle iron is placfd on top ends of the` studdings 17 and having a downwardly extending flange 20 secured to the upper edges of the flanges 18 by means of rivets or other fastening means.

Secured to the flanges 18 of the studdings 17 is a series of sheet metal slats 21, each of which comprises a body portion 20a terminating in inclined portions 22 and 23bent to an angle of substantially 45 to the body. -The edges of the inclined portions 22 and 23 terminate in portions 24 and 25 parallel with the body 20a. The edges vof the portion 24 are bent upwardly and outwardly at an angle of substantially 45 to form a flange 26. The edge of the portion 25 is'bent downwardly and outwardly to form a flange 27 also at an angle of substantially 45. The flange 26 is of a width substantially half the width of the flange 2'?.

'I'he slats 21 are'supported on the studdings 17 by means of rivets or other fastening means 28 with the flange 27 of the lower slat overhanging the upper edge of the flange 15 of the angle 13. 25 A second slat is then placed on the studdings above the first slat with the flange 27 .overhanging the adjacent flange 26 in the manner clearly illustrated in Figure 2, so that the lower edge of the flange 27 terminates substantially in a plane including the outer surface of the flange 26, and with an air space 29 between said flanges. Any number of these slats may be placed on the studdings until the entire wall surface Ihas been covered. y

By constructing the slats as above described, it will be seen that longitudinal depressions 30 are formed in the outer surface of the slats and adjacent to each of its longitudinal edges. This formation greatly stiflens the Slat and at the same time provides means for preventing rain or snow from entering the interiorof the building.

Furthermore, the longitudinal depressions terminating in the. outwardly inclined flanges providesV means -whereby air vcurrents directed against the outer face of the wall will have a tendency to create outwardly flowing currents at a point near the edges of the flanges, so that in most instances a draft of air will be caused to move outwardly from the building rather than inwardly.

Currents of air striking the wall of the buildingfrom above will tend to move in a line indicated by the arrows 31, and be swept over the lower edges of the members 27, while upwardly of the members 20 wi inclined currents striking the face of the building will have a tendency to move over the flanges 26 in the manner indicated by the arrows 32. In either event rain would not be driven into the building, which is a very desirable feature in ventilated wallconstructions, especially when sheet metal is utilized for forming the slats; inasmuch as the thickness of the sheet metal is thin compared to the ordinary board construction.

It will further be. seen that the anges terminate outside of the portions 24 and 25 a considerable distance so that grain, such as ear corn, when placed in the building will engage the inner surface oi' the portions 24 and 25, and the inner faces thcut engaging the ends of the anges 26 and 27, so that water clinging to the ends oithe ilanges would not make direct contact with the corn or similar grain.

'I'he corners of the walls may be formed with vertically arranged angles 33 to which the ends of the members 24 and 25 may be secured. A nishing strip 34 may be provided forthe outer surface of the corners.

Thus it will be seen that I have provided a rigid and comparatively cheap wall construction particularly adapted for corn cribs and provided with means for Ventilating and at the same time prevents elements of the weather` from entering the building.

By providing the packing strip :12, the sheet metal wall construction may be set on a comparatively uneven concrete foundation without setting up undesirable strains in the steel structure. 'I'he packing also prevents moisture from making contact with the under. surfaceof the angle 13 Vfrom the -concrete wall.. It also protects the metal from destruction due to the alkaline condition of the cement foundation.

I claim as my invention:

1. A sheet metal slat comprising a body portion having its upper and lower edges terminating in ing in portions parallel with the body portion, the

edges of the last said portions terminating in oppositely inclined portions substantially perpendicular to the iirst inclined portion, one of the lasst said inclined portions being wider than the o her.

construction comprising? 3. A sheet metal slat comprising a body porl tion having its upper and lower edges terminating in oppositely inclined and diverging portions, said inclined portions terminating in portions parallel with the body portion, the edges of the last said portions terminating in oppositely inclined portions substantially perpendicular to the rst inclined portion.
